what was the ball average speed during the time represented in the graph.
HINT; Divide rise/run Distance/time
what was the ball average speed of the toy car during the two trials to the nearst tenth of m/s
HINT: Add all distances add all times then divide distance /time. then round your number
which cart will result in the greatest change in speed.
what was the average speed between the first 40 seconds.
HINT; Divide rise/run Distance/time
a bus travels 20 km in 30 min. what is average speed of the bus.
HINT: change your units from minutes to hours by dividing time by 60. then calculate speed.
based on the data in the table ,which object experienced the greatest force.
HINT: use F=ma triangle
Ablock is pulled 0.5 m to the right in 4.67 s.
what is the ball average speed to the nearst hundredth of m/s.
.A baseball player hits a baseball with a bat. The mass of the ball is 0.42 kg. The force of the bat hitting the ball is 30 N. What is the acceleration, to the nearest hundredth m/s2, of the baseball?
Hint :Use f=ma triangle to calculate you acceleration .
A bus travels 30 km in 30 minutes. What is the speed of the bus in km/h?
An elephant pulls a 700-kg load with an acceleration of 1.5 m/s2. How much force did the elephant apply while pulling the car?
which of the following match speed,velocity and acceleration?
Hint: Velocity is Speed+direction
Acceleration unit is m/s2
How much force is required to accelerate a 22 kg mass at 1.3 m/s2?
what is the ball average speed between 20 and 60 seconds.
Hint : the car stayed at the same distance Rise=0
what is the difference in speed of ball A and ball B ? round to the nearst tenth place.
HInt: Find speed A then Speed B then subtract the 2 numbers .
what was the average speed to the nearst tenth of m/s?
